I always felt proton torpedoes weren't shown launching the important fatal blows to the Death Star in the original version of "A New Hope" due to budgetary or time constraints. And I hoped they would be shown in the SE or in the "Revisited" fan edit/reconstruction, but they weren't.
New shot(s) of them launching would give a great reference point for the difficulty of the shot on the target as well as show where the heck they're coming from. So that's my challenge to everyone out there creating new edits of the movie.
Oh, and replace those dopey shots of TV switcher controls for the Death Star firing sequences. Takes you right out of the movie.
